Later this morning, President Obama will nominate Solicitor General Elena Kagan to replace retiring Supreme Court Justice John Paul Stevens. The Senate confirmed her appointment to her current position last year, 61-39. Justice Stevens has long been a reliably liberal voice on the court and Kagan would likely continue that philosophy. If confirmed, she would be the third woman on the court and the first justice in nearly forty years who has not already served as a judge.

Jeffrey Rosen, law professor at George Washington University tells us more about the nominee.
